If you don't find any let me know...I added veronia narbonences (not sure I spelled that correctly, sorry), this past summer but didn't get flowers, should next season tho...Also Veronicastrum, white and purple...( veronicatrum is a veronica on stilts...lol...pix is veronica)...
With me we are back to common,, You are showing or talking about Speedwell? Like Longifolia? How tall does this get?
Your offer looks good to me like it might fit into some tall plants '
Mid summer blooms?
Vernonia gigantea A place to have a look see...
Oh, gosh I'm sorry to confuse you..lol. What I meant on the veronicastrum is it's also another tall us. native, the flowers are very similar to Veronica spicata, but veronicastrum is 48+ tall. That particular Veronica is probably the tallest that I have found, (hasn't been on the market as a plant yet, but got seed from T&M seeds more than 10 years ago and now is not even available), have some if you wanna try.
And yes That's the veronia I have...lol. Like I say, I'll collect seed this summer.
Thanks to both of you...lol, it's not my pix tho...shhhh. When at my daughter's house I use their's ...lol. (Yup, all pix of the mountains are here in Colorado). I told my daughter the other day they need to get some new ones this summer...lol. How bad is that?
